Define yourself like how they define a word on the dictionary.....?

You are defining your personality and interests. But “you” consist of more possible definitions depending of the person’s perspective. You can’t just define yourself just by those words. Someone else could have had the exact “definition” as yours; therefore it’s not a definition. Your interests may not define you as a being. For example, did you like history when you were five (false statement)? Would you have the same interests if you were born somewhere else (environmental)? The only way I could define myself is my gene code as my physical and psychological being , and I don’t have anything to proof that my soul exist, so it remains undefined.
